Earth's spin warps space around the planet, according to a new study that confirms a key prediction of Einstein's general theory of relativity.
After 11 years of watching the movements of two Earth-orbiting satellites, researchers found each is dragged by about 6 feet (2 meters) every year because the very fabric of space is twisted by our whirling world.
The results, announced Wednesday, are much more precise than preliminary findings published by the same group in the late 1990s.
The effect is called frame dragging. It is a modification to the simpler aspects of gravity set out by Newton. Working from Einstein's relativity theory, Austrian physicists Joseph Lense and Hans Thirring predicted frame dragging in 1918. (It is also known as the Lense-Thirring effect.)
Here's how it works:
Any object with mass warps the space-time around it, in much the same way as a heavy object deforms a stretched elastic sheet, explained study leader Ignazio Ciufolini of the Università di Lecce in Italy.

Yes, Ive read of this before. Einstein was at least 100 years ahead of his time of you ask me. Simply amazing what this man could do.

I'm not sure it's just the mass. I think the fact that the mass is spinning also has something to do with producing the "warping". Of course, is there any large (ie: planetary size or larger) body that ISN'T spinning? I think this tells us something, but I'm not sure what.
